About the Splitflap controller board

Splitflap controller board is an open source AVR/Arduino PCB design by orgTestCodacy11KRepos110MB, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 96 × 48 mm, with 33 components from 19 distinct parts.

Its main chip is the arduino_uno_shield, from the AVR/Arduino family. Other key parts include the MIC5842, 74HC165 and WS2812B. By type, the board carries 10 connectors, 8 ICs, 8 resistors, 3 capacitors, 2 diodes and 1 jumper.

It belongs with the displays & leds and wearables designs in this gallery.

From the project

This is a DIY split-flap display. Prototype four-character display: video.

This is a DIY split-flap display. Prototype four-character display: video.

The goal is to make a low-cost display that's easy to fabricate at home in small/single quantities (e.g. custom materials can be ordered from Ponoko or similar, and other hardware is generally available).

You can view an interactive 3d model of the design on the project website.

The splitflap community Discord server is the best place to keep up with the latest changes or ask questions about the project!

Splitflap controller board: common questions

What microcontroller does the Splitflap controller board use?

The Splitflap controller board is built around the arduino_uno_shield, from the AVR/Arduino family.

How big is the Splitflap controller board?

The Splitflap controller board measures 96 × 48 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Splitflap controller board?

33 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Splitflap controller board design files?

From the orgTestCodacy11KRepos110MB/repo-1066-splitflap repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Splitflap controller board design in my own project?

Yes, under the terms of its Apache-2.0 license, which orgTestCodacy11KRepos110MB chose for the repository.

Can I test firmware for the Splitflap controller board without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
